菲涅耳波带片可使入射光会聚起来，产生极大的光强，使点光源形成一系列的实像点和虚像点，其作用如同透镜成像。利用半波带分析法可分析菲涅耳波带片对称轴上的点光源通过菲涅耳波带片成像时像点在对称轴上的分布及 焦距的变化情况。     

The Uncertain Future for Digital Visual Collections in the University

Digital documents in the networked information environment fundamentally change the ways that visual materials can be used in education and scholarly discourse. These new uses raise questions about research library strategies with regard to digitized visual materials as a part of their collections, challenge assumptions underlying intellectual property rights for images and their scope, and offer ways in which visual literacy can become a more integral part of the common educational experience.     

文学欣赏的境界

文学欣赏是一种特殊的精神活动,达到的是一种精神升华的境界。在欣赏过程中,欣赏者注视着的是具体的艺术形象,文学欣赏是对形象艺术的感悟过程,在这个感悟过程中,欣赏者应始终是对文学作品的整体艺术的感受,而不是局部的寻章摘句,如仅仅盯住某个细节、某个动作,就不能感受到整部作品的特征。从某种意义上讲艺术作品创造欣赏者,因此,在进行文学欣赏时,一定要选择最为优秀的作品,——“取法乎上”。

Exploring Verbal,Visual and Schematic Learners' Static and Dynamic Mental Images of Scientific Species and Processes in Relation to Their Spatial Ability

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners.
